I think a lot is priced in already...
Segwit activation - priced in
Lightning network - priced in
Some developers switching to Litecoin to build on top of Segwit enhancements - priced in
Litecoin on Coinbase - priced in
Litecoin on Trezor - priced in
So the LTCBTC price will likely fall for a while.
However some of the implications of Segwit are not fully understood yet, nor are the many benefits of LN. These advancements are full steam ahead now and Charlie Lee has shown he is very open and even involved in moving things forward.

https://twitter.com/dieguito/status/857564092583858177I'm quite optimistic but under no illusions, the Litecoin price is still very fragile and $6-10 or 0.006 - 0.008 might be a good entry if it falls that low again. But I would start dipping your toes in now because crazy things can happen when the underlying technology allows it.
